Minor correction - Gandhi wasn’t assassinated for sending in peacekeepers. It was for sending in and leaving unchecked a notoriously brutal “peacekeeping” force who terrorized the people they were there to protect: https://en.wikipedia.org/wiki/Indian_Peace_Keeping_Force#War...
As a former resident of SL, it’s easy to point fingers at the ousted regime. Corrupt and made disastrous decisions for the economy, but there are far deeper problems.
The country’s politics revolves around weaponized Buddhist fundamentalism (the same flavour you see in Myanmar). For 70 years, it has just been politicians gaining by encouraging inter-ethnic conflict. The current regime was voted in based in strong anti-Muslim rhetoric. Soon, there will be another similar leadership. Until that changes, this country is no different than Afghanistan under the Taliban.
Tourism has been the saving grace, but the 2019 bombings and pandemic mean it will likely never recover. At some point, change has to come from within.
Quite justified in my opinion.
